微波炉消解原子吸收法测定铜精矿中多元素

Microwave Digestion of Copper Concentrates for AAS Determination of Metal Elements

摘要: 研究了用微波炉消解铜精矿,原子吸收光谱测定其中As、Pb、Zn、As、Sb和Hg的方法。讨论了消解体系的选择和微波炉消解程序。样品经HNO_3-HCl一次消解便可连续测定6个元素,方法简便快速,与国标方法进行了比较,结果一致。

Abstract: The heating process and the selection of digestion system were discussed. Following direct decomposition with HNO3-HCl,Ag,Pb,Zn,As,Sb,and Hg were determined by AAS sequentially on a single solution. This method is rapid and simple. The results obtained by
